Woocommerce disable payment gateway by shipping method

Hi,

i’m currently running a wordpress+woocommerce site, and i want to disable Cash On Delivery based on Shipping Method select.

I’ve seached and found another tutorial on how to do this, but based on country selection only. (https://stackoverflow.com/questions/17015173/how-to-hide-payment-method-in-woocommerce-based-on-postal-code)

I tried to edited this code, but with no sucess.

The diference is that i use the table rates plug-in, and i want to disable the cod option based on my shippinh selection (in this case the shippinh method id is table_rate-3)

I’m really stuck on this

Thanks in advance for any help
